摘要: 大型海藻是近岸海域重要的初级生产者,近年来人们愈来愈认识到大型海藻在近岸海域富营养化生物修复中的重要性,同时,富营养化也可能招致某些机会主义大型海藻种类的爆发生长,因此,进一步理解大型海藻与营养盐供应变化的关系就显得非常重要。本文从大型海藻营养盐代谢与海水中营养盐供应变化(主要是富营养化)的生理生态关系角度对相关问题进行评述,主要包括影响大型海藻营养盐吸收特性的重要因素、海水中营养盐的供应及大型海藻对营养盐的细胞贮存、大型海藻对营养盐的生态需求、大型海藻对近岸海域富营养化的生态响应等问题。文章还对今后的研究提出了展望。

Abstract: Marine macroalgae are the important components of coastal primary productivity, playing a key role in the coastal carbon cycle. In recent years, there is a growing recognition that marine macroalgae could be a good solution of bioremediation to the problem of coastal eutrophication. Coastal eutrophication may lead to the excessive growth in some species of opportunistic macroalgae. Therefore, it is essential to further understand the relationships between marine macroalgae and changes of nutrient supply. This paper reviewed the related ecophysiological issues on the relationships between macroalgae and coastal eutrophication (increasing nutrient supply in seawater), with the focus on the factors affecting the characteristics of nutrient uptake by marine macroalgae, their intercellular storage of nutrients, ecological requirements of nutrients, and ecological responses to the coastal eutrophication. The prospects for future research werealso discussed.
